Charged EVs | New study: 10 percent EV penetration could shift utility’s entire peak load

Driving a PHEV has taught me that, for daily commutes, "lack of charging infrastructure" isn't really a thing. The charging infrastructure already exists. It's the electric service to your garage or carport. Come home, plug in, and wake up to a full "tank".

Plug-in vehicles that arrive home with some charge remaining can even solve a problem for the grid as a whole, by reducing peak demand. Just add vehicle-to-grid.

Charged EVs| ... 10% EV penetration could shift utility’s entire peak load:

“We were surprised both at the relatively small 10 percent EV market saturation required to completely clip the SCE residential peak and the large annual savings…even after paying for nighttime recharging,” Jackson Associates President Jerry Jackson told Utility Dive.

BEV, ICE and Cobalt: an illuminating Twitter thread

Thanks to Robert Llewellyn for resuscitating the following Twitter thread. Unfortunately, the thread is so old that neither Thread Reader App nor Twitterrific is able to retrieve it. Twitter's web interface can still retrieve it, so I've taken the liberty of transcribing it below.

Synchronicity on Twitter: "The Dirty Secrets of #ICE - Part 1..." / Twitter:

The Dirty Secrets of #ICE - Part 1 Whenever there’s a debate about the benefits of battery electric vehicles #BEV vs internal combustion engine #ICE vehicles, one of the 1st things usually mentioned is cobalt with lurid stories such as linked here.
But when you fill your tank with petrol or diesel did you know that cobalt is used as a key ingredient?
When we figured out that sulphur in our fossil fuels was a key component to acid rain (remember acid rain?) & also contributed to serious health issues it was decided that ultra low sulphur fuels was the way to go. But the catch is that removing sulphur during the refining process is actually quite hard. You need something to act as a catalyst to aid the Desulphurisation process. So they added a metal to kick start the key reaction.
And yes, the metal they add is cobalt. Here’s the lowdown from the “Cobalt Institute” (cont) https://cobaltinstitute.org/desulphurisation.html
It’s a long and detailed article but the key information is in the first few paragraphs.
So to make low sulphur petrol & diesel, which is the global standard now, they must add cobalt during the refining process. Yes, but that cobalt doesn’t get into the final product we put into our tanks right? Right?? Wrong!!! In fact a lot is left in the final output.
Check out the list of toxins and carcinogens that make up ordinary everyday diesel exhaust emissions for instance. Yes it’s a long list of nasties but look who’s there? Yes, it’s our friend cobalt.
So when the anti-BEV lobby start shouting about cobalt in batteries, tell them about the cobalt in their fuel. At least the cobalt in the battery *stays* in the battery and can be completely recycled. The cobalt in their fuel is spewed out the exhaust for our children to breathe.
And then we should consider how Cobalt relates to EV batteries. So this from Amnesty International confirms that about 20%, at most, of the cobalt from the DRC is hand mined. The rest is machine mined.
Overall, about 60% of the world’s supply comes from the DRC. So that means only about 12%, at the very most, of the global supply of cobalt is actually hand mined. Also add that a lot of that cobalt is used for other things like high quality steel, and the fact that a lot is also used in cell phone, tablet, laptop batteries, and petrol/diesel fuel of course, and that the amount of cobalt actually in EV batteries has fallen dramatically. The chances of hand mined cobalt getting into your EV battery is next to nil.
So it’s just disingenuous & misleading to link unethically sourced cobalt solely with EVs when in reality it’s used for a lot more other applications in every part of our society. But of course it serves many parties with anti-EV interests for that false association to be made.
Some selected replies:

simon blackmore @blackmore_s Jun 20

#FFS the #FUD they peddled about BEV's battery chemistry and they are pumping that crap into the air via exhaust fumes.

DIYMicha @DIYMicha Jun 22

... and cobalt is an ingredient in hardened high temperature steel, used in valves and valve seats of ICE engines.

Synchronicity @Synchronicity34 Jun 22

Yes indeed, mentioned further down in the thread.

Synchronicity @Synchronicity34 Jun 21

But the cobalt in batteries stays in the batteries and is then recycled. The cobalt in fuel is distributed though our most populous cities, day upon day, accumulating on our streets, in the air, in our children’s lungs. Which source should you be most immediately worried about?

Synchronicity @Synchronicity34 Jun 21

Key research on the long term cumulative effects of our children ingesting heavy metal particulates such as cobalt are only just starting. I don’t think you are qualified to say whether any other issue is bigger.

A World We Built to Burn - Quinn Norton

A World We Built to Burn | emptywheel:

So here we are: Keeping the lines on will probably kill people. Turning them off will probably kill people. Our political system is facing a real-life trolley problem created by our ever-expanding technical debt. It can’t have been easy for the people making the decisions.
One of our jobs in this century is to accept that we don’t live on the planet we thought we lived on, and our societies aren’t doing what we thought they were. Even if we were able to change our politics overnight, which is probably impossible without some planetary level disaster wake up call, it would still take many decades to dig ourselves out of out technical debt, and in the mean time, we have to stay alive and try to thrive.
I can imagine you looking at the screen, saying “It shouldn’t be this way!” But it is this way. The world we thought we had, with a safe stable environment and not too many people, that is not the world we live in. That is, in short, not real. At the individual level as well as the policy level, we need to let go of that which is not real.
Framing a mesh of interrelated social, political and environmental problems as technical debt is brilliant. Finding it on emptywheel, a site that I visit for its insights into the takeover of our federal government, is surprising but welcome.

Climate change: Bill McKibben’s advice for activists - Vox

Climate change: Bill McKibben’s advice for activists - Vox:

Sean Illing
I worry a lot of people have trouble connecting the dots between these food supply disruptions and the political chaos that results from them. For instance, you point out how a 2010 heat wave in Russia, which wrecked their grain harvest, led directly to the Arab Spring. How did that happen and what are similar scenarios that could play out in the near future?
Bill McKibben
That happened because the Arab world is the biggest importer of grain from eastern Europe and when the price went way up for a loaf of bread, the predictable trouble ensued. Probably an even more dire example is what happened in Syria. In the early part of this century, we had the deepest drought ever recorded in the Fertile Crescent. That drove an immense number of Syrian farmers, maybe a million farm families, off their land and into the cities.
And there’s been a lot of academic work to establish that that was one of the key things that triggered the civil war (here and here). Syria was already a brutal and unstable place, unable to cope with this massive influx of people. And so many of those people were spun out into the rest of the world where they utterly discombobulated the politics of Western Europe inside of 18 months.
So we can look at what happened in Syria and Europe and expect much more of that in the century ahead. And I think the low end is 200 million climate refugees and the high end approaches a billion. So take the kind of upheaval that the wave of refugees out of Syria created and multiply it by a couple of hundred and ask yourself how that’s going to impact war and peace, or development, or any of the other things we desperately care about?

New Mexico seeks energy savings in state building upgrades | Local News | santafenewmexican.com

New Mexico seeks energy savings in state building upgrades | Local News | santafenewmexican.com:

New Mexico is pushing forward with multimillion-dollar, energy-saving upgrades to its portfolio of agency buildings in the state capital, as part of an emerging climate-change strategy from Democratic Gov. Michelle Lujan Grisham.
The General Services Department which oversees more than 800 buildings plans to invest $32 million on projects to improve the energy efficiency of state buildings in Santa Fe and generate on-site renewable electricity with photovoltaic solar panels.
The state government’s first battery storage for solar energy is part of the project.
State legislation approved this year provides $20 million in direct spending on the energy upgrades at state buildings.
The contractor hired to implement building improvements in Santa Fe has guaranteed energy-related savings of $1.1 million a year... The state expects actual annual savings of about $1.4 million.
Separately, General Services said it has received $1 million in state funds to purchase electric vehicles for use by state workers. Another $1.5 million is going toward the creation of vehicle charging stations at state facilities within Santa Fe County.
It's very encouraging to see all of this. Thank you, Governor Lujan Grisham.

North Carolina Orders Duke Energy to Excavate All Coal Ash - The New York Times

Michael Shellenberger has observed that, of all current types of electricity generation, only nuclear has the cost of waste management included in its price. Now some of that cost is being rolled, almost retroactively, into the cost of electricity from coal. North Carolina Orders Duke Energy to Excavate All Coal Ash - The New York Times.

2019/04/01

Is Nuclear Power the Key to Finally Reducing the CO2 Footprint?

NB: These are essentially the same points Michael Shellenberger makes, but they come from a different source. Is Nuclear Power the Key to Finally Reducing the CO2 Footprint?:

In about 20 years, at a cost of at least two hundred billion dollars, it has added about 80 gigawatts of wind and solar generating capacity—enough in principle to cover its winter peak—to its energy mix, an amazing feat in itself.
the International Energy Agency shows that the amount of CO2 generated per kWh of electricity in Germany is still about 480 grams, despite their large investment in wind and solar technology. The reason is that the country still relies on coal and natural gas for about half of its electricity, as its wind and solar fleet lay idle most of the time. In the meantime, France—which relies on nuclear power for 75 percent of its electricity—generated only about 70 grams of CO2 per kWh. When France decided to go nuclear after the first oil shock in 1973, it derived about two thirds of its power from coal and oil-fired power plants and emitted 500 grams of CO2 per kWh. Twenty five years later, its power sector was almost carbon-free.
Because of its reliance on nuclear power, France currently has one of the lowest rates of CO2 emissions per kWh in Europe. Every year, the French power sector emits approximately 260 million fewer tonne (metric ton) of CO2 than its German counterpart, despite similar productions (respectively 560 billion kWh and 630 billion kWh). This is equivalent to taking 175 million cars off the road (assuming an average emission of 0.15 kg-CO2 per car and per km and 10,000 km per car and per year)—about 75 percent of the whole European fleet of personal vehicles.
Delays in implementation caused by legal and regulatory issues—in particular those associated with long-term liability—are likely when it comes to choosing the sites that will have to permanently host billions of tonnes of CO2. Such delays have been happening for the geological disposal of used nuclear fuel. However, unlike used nuclear fuel, which can be safely stored at reactor sites while waiting for a final disposal solution, CO2 is currently released to the atmosphere until a final solution emerges—which could take a while.
After more than two decades spent analyzing available data, experts from institutions such as the World Health Organization and the United Nations Environment Program, concluded that 43 people died of causes directly attributable to the Chernobyl accident. They also indicate a potential 3 percent increase in cancer mortality in the 600,000 most exposed people. In such a large population, unfortunately, more than 120,000 lethal cancers are expected to occur spontaneously—independently of any radiation exposure—and the Chernobyl accident may add 4,000 cases to this macabre toll. However, a long standing issue associated with this predicted increase is that it cannot be verified with certainty because it is much smaller than—and mostly undistinguishable from—the background of spontaneous cancers.
Finally, whereas most of the general public will very likely point at the Chernobyl and Fukushima accidents as the worst modern science and engineering failures, only very few will remember the 1975 collapse of the Banqiao dam (China) where approximately 26,000 people died from flooding and another 145,000 died because of epidemics and famine. Another dam, Machchu-2, in India also failed a few years later (1979) killing at least 2,000 people. Experience shows that nuclear power does not entail more risk than other industries.
Assuming a typical consumption of 7,000 kWh per year, a person living in San Francisco would be responsible for the production of about 6.2 cubic centimeters of used nuclear fuel per year weighing 18 grams if the electricity came only from a nuclear power plant. It would take about 55 years for this person to fill the equivalent of a can of soda with used nuclear fuel. So, yes, these used fuel assemblies contain very dangerous materials—standing next to one, unprotected, would kill you in a few minutes—but there is very little of it. If the same electricity had come only from a gas—natural or bio—power plant during the same 55 years, that person would have been responsible for the emission of about 190 tonnes of CO2—900,000 cans of soda or one every half-hour—and twice that amount if it had come from a coal power plant.

In New Mexico, renewables don't always mean clean energy | Local News | santafenewmexican.com

2008 brought plans to erect wind turbines across the Taos plateau. Last year long-distance transmission lines were ready to carry wind power across the bird migration routes near the Bosque del Apache. And now this: a geothermal plant may be harming an aquifer in New Mexico's Animas Valley. This is an interesting read from the Santa Fe New Mexican, about roses, tilapia, politics and energy politics: In New Mexico, renewables don't always mean clean energy | Local News | santafenewmexican.com:

Riding his horse through cattle pasture of brush and brittle mesquite, Randy Walter spotted a 10-foot geyser spewing from a well that had been capped and padlocked for 12 years.
The dark side of renewable energy is that every form of production carries its own environmental baggage.
During the 2012 legislative session, Southern New Mexico Democrats Sen. John Arthur Smith and Rep. Rudy Martinez co-sponsored a bill that took jurisdiction over 250-plus-degree water from the Office of the State Engineer and placed it in the hands of the Oil Conservation Division.
In other words, the hot water was no longer considered water, but energy. The agency historically tasked with managing water in New Mexico was stripped of its authority over the project.
One of the people unafraid to speak out is Meira Gault, a 69-year-old cattle rancher who once served in intelligence in the Israeli Army and has been a Hidalgo conservation district official for 11 years.
Gault said she views the well blowout as the surest sign that the geothermal water simply isn’t going where Cyrq promised it would go.

Lightning Strike Prototype Review - Cycle News

I've complained since the invasion of Kuwait that the U.S. was missing an opportunity to develop energy-efficiency technology - that the rest of the world would pay to buy. Of course I missed the idea of developing "alternative" (non-fossil-fuel) energy tech, etc. Anyway, this is encouraging news: some U.S. businesses are intent on doing exactly that. Witness Lightning Motorcycle Group: Lightning Strike Prototype Review - Cycle News:

...we think India will be right there with [China, as a market], basically to address the environmental problems that they face at present...
the two largest motorcycle markets in the world will both predominantly focus on electric motorcycles in the coming years, and Lightning will be there to serve them.

Amazon is cleaning up (its act)

After almost a decade I may be able to rejoin Amazon Prime. (Yes, I'm a self-congratulating hypocrite.) It bugged me that they never published the relative carbon costs of Prime vs. std shipping. Now, within the last couple of weeks, they're:

  1. stating goals for carbon-neutral ops
  2. investing in Rivian
  3. hiring away at least one GM executive
  4. offering Prime members "one day a week" bundled deliveries (which sounds much the same as std shipping ;))

Plummeting insect numbers 'threaten collapse of nature' | Environment | The Guardian

Plummeting insect numbers 'threaten collapse of nature' | Environment | The Guardian:

“The main cause of the decline is agricultural intensification,” Sánchez-Bayo said. “That means the elimination of all trees and shrubs that normally surround the fields, so there are plain, bare fields that are treated with synthetic fertilisers and pesticides.” He said the demise of insects appears to have started at the dawn of the 20th century, accelerated during the 1950s and 1960s and reached “alarming proportions” over the last two decades.
He thinks new classes of insecticides introduced in the last 20 years, including neonicotinoids and fipronil, have been particularly damaging as they are used routinely and persist in the environment: “They sterilise the soil, killing all the grubs.” This has effects even in nature reserves nearby; the 75% insect losses recorded in Germany were in protected areas.
... organic farms had more insects and that occasional pesticide use in the past did not cause the level of decline seen in recent decades. “Industrial-scale, intensive agriculture is the one that is killing the ecosystems,” he said.
“When you consider 80% of biomass of insects has disappeared in 25-30 years, it is a big concern.”

The Green New Deal, explained - Vox

<humor>This wide-ranging article leaves the impression that the Green New Deal is, like the article itself, doomed by its broad scope.</humor> I will randomly quote one of its many interesting points.

The Green New Deal, explained - Vox:
... climate change impacts are going to cost more than climate mitigation anyway. The GND is big, but “big things will happen,” says Chakrabarti. “The two options are, either we’re going to intentionally do the big things we want, or big things we don’t want will happen to us.”

We're screwed if we do nothing. Might as well find some interesting weak spots and start working on them.

Play Bill

I sometimes have trouble keeping track of people quoted in articles. Here's a playbill for this one.

People

Evan Weber: a co-founder of the Sunrise Movement.

Rhiana Gunn-Wright: a policy analyst employed by the nascent New Consensus.

Saikat Chakrabarti: Chief of Staff to U.S. Rep. Alexandria Ocasio-Cortez, and a co-founder of Brand New Congress.

Greg Carlock: a researcher, essayist and podcaster who writes about U.S. policy, governance, climate change, the Green New Deal, and political philosophy. Currently works for Data for Progress. If he were a software developer, I think he would be an advocate for rapid prototyping; the article quotes him as favoring the method (for new policy/programs) of "Pilot and scale".

Organizations

Sunrise Movement: a youth-led organization advocating for a Green New Deal (bold climate action coupled with efforts to address worsening social inequities).

Data for Progress: bills itself as "the think tank for the future of progressivism", and as representating citizens who believe in Medicare for all, a Green Job guarantee, and the abolition of ICE.

New Consensus: a policy non-profit that identifies itself as follows:

We are a global, distributed network of academics, creators, activists, leaders and entrepreneurs working to make the new consensus the standard operating system for national economies around the world.

Brand New Congress: an organization founded after the 2016 elections with the goal of recruiting 400 "fresh new faces" to run for Congress.

Notes on the Fickle Fortunes of Bighorns

"Running With The Herd: A NATURE Short Film" meshes with some recent reading. Rough notes follow.

Flickr

In 2010, on Flickr, I saw photographs of bighorn in the Rio Grande Gorge, taken by a river guide. This created a tiny ambition to see them for myself.

On July 4th, 2011, I took a walk along the West Rim Trail, not really expecting to see anything - after all, this trail is more than 700 feet above the box. But I was lucky, and I got to spend a half hour or so watching three ewes and a lamb feed near the edge of the rim.

A couple of months later I returned and, in nearly the same spot, was stopped in my tracks by three young rams, who grazed right up to where I was standing.

Bighorn

In October, 2012, my luck wasn't so good. I saw only one ewe, from such a great distance that I could barely tell that she was a sheep. Reviewing the photos later, I could see that she was carrying a radio collar.

Why was she wearing a collar? What was the story of interactions between humans and these impressive creatures who, until I saw that collar, I had imagined to be completely wild?

New Mexico Wildlife Center

On July 4, 2015, I was finishing my volunteer shift at the New Mexico Wildlife Center. As I walked out to my car I was met by a weary, late-middle-aged couple. I thought they were going to ask if the Center was open. Instead the lady explained that they had called ahead and were delivering a baby robin, which the man had been hand-raising for the past several days.

This turned out to be one of the most enjoyable afternoons of my recent life. Maybe I'll write it up sometime. For now, the important part is that we passed the next hour or so on the front porch, talking about our respective wildlife encounters.

The man had spent plenty of time watching bighorns in the Taos mountains. And he knew a fair bit about how they had come to be in the Gorge. He explained that they had been introduced only recently, around 2008.

He also told about the old New Mexican sheep herders whom he had befriended when he first moved to Taos, and about the bajadas - the trails – they had used to bring their herds down to the river to drink.

Those bajadas have created a little romantic fantasy in my imagination. The sheepherders are gone, but those trails are still used. I have followed bighorn tracks down some of them. The enduring picture is of a succession of wild sheep, then domestic, then wild again, all finding the same paths down to the water.

Last year I found an article in the Taos News that fleshed out the man's story about how the bighorn came to live along the Rio Grande:

Much like the river otters that now swim in the river at the bottom of the gorge, bighorn sheep were — up until not that long ago — a big part of the order of things in the southern stretch of the Rocky Mountains we call home.

(River otters! That was another wonderful, lucky encounter for me, and the resulting video brought me into contact, through iNaturalist, with one of the people who had helped reintroduce them into the upper Rio Grande. But I digress.)

According to Eric Rominger, bighorn sheep biologist for the New Mexico Department of Game and Fish, bighorns were extirpated in New Mexico around the turn of the 20th century. The last known evidence of a bighorn in New Mexico was a track found in the Truchas Peaks south of Taos.
The reintroduction of the bighorn sheep started in the 1940s when a group of sheep were gathered from Alberta and brought to the Sandias. A herd was started in the Pecos Mountains with a mix of fresh blood from Alberta along with a few Sandia sheep — the founding stock for many of the rest of New Mexico’s herds.
Sheep from the Pecos were brought to the Wheeler Peak Wilderness in 1993. As Michael A. Martinez, hunt coordinator for Taos Pueblo’s wildlife office, said, “Of course, they eventually made their way on the pueblo side. The majority of those bighorns winter on the pueblo side’s abundance of south-facing slopes, moving back to the public side during the summer.”
Then, in 2005, the Taos Pueblo war chief, lead biologist and director of wildlife decided to try to bring the bighorns back to the inverted mountain landscape of the gorge. Taos Pueblo took an initial group of sheep from its side of the Wheeler Peak chain, and the state department supplemented the herd in 2007 with more sheep from the Pecos.

This must be the best combined job title in the world: "Taos Pueblo war chief, lead biologist and director of wildlife."

It bears repeating: I'm deeply grateful for all that Taos Pueblo is doing to care for their home. Bighorn, otters, advocacy for creation of the Rio Grande del Norte National Monument - who knows what else they are doing? The main aim may be to take care of the land, but in doing so they've made it possible for mere mortals to stumble upon amazing animals while out on a day hike.

Beatty's Cabin

This fall I made my first treks into the Pecos north of Cowles. I'd seen photos and video from near the Truchas peaks, of human encounters with proper mountain-dwelling bighorn. I was hoping for similar luck.

Please don't hound the sheep

Alas, the only bighorn I came across had already had its own, horrible meeting with humans.

Feast

This year, through a series of lucky accidents, I finally learned about the book "Beatty's Cabin". It's a great, revelatory book. (The web carries several wonderful stories about its author, Elliott Barker, who in his lifetime seems to have regarded the Pecos as his ideal place on earth.)

"Beatty's Cabin" backs up the details of the Taos News article. Like the Nature short film, it explains how bighorn have been harmed both by hunting and by close encounters with domestic sheep.

The Rocky Mountain bighorn sheep, also, were indigenous to this and other areas of the state but their meat was considered the best of all wild meat and, hence, they were sought after like select items on a bargain counter.
In 1873, Coues and Yarrow reported sheep were plentiful in the mountains east of Santa Fe (the upper Pecos) but they were to disappear rapidly after that. Tom Stewart told me many times that the last mountain sheep killed in the area was taken by Jim Bullock at the base of Santa Fe Baldy; near Lake Katherine, in 1902; however, naturalist Vernon Bailey reports in his Mammals of New Mexico that he saw unmistakable tracks of mountain sheep in the Truchas Peaks area in 1903.
It is most probable that rifles were not the sole cause of the depletion of these denizens of the high, timber-line area. When domestic sheep were brought into the high country to graze for brief summer periods, they were often infected with scabies and, perhaps, other communicable diseases or parasites which could easily be transmitted to the bighorns. Domestic sheep could be cured of scabies by forcing them to swim through vats of Black Leaf 40 solution, but Nature provided no such method of treatment for the wild bighorns, and they would be defenseless against the ravages of parasitic infections or diseases new to them, just as the Indians were against smallpox, first brought to them by the white man.

"Beatty's Cabin" ends its story of the bighorn in New Mexico with a statement of hope, one that appears to have been fulfilled.

... with the untimely passing of these spectacular creatures, the jagged crags and templed peaks very definitely lost something of their hereditary charm and glory. On timber-line ridges and in the coves, alpine clover each year sends up its velvety, gray-green leaves and pink-white blossoms in supplication for the return of God’s free wild creatures who once fattened upon its succulence. But none return to eat it. The brows of the high, grassy hills, furrowed and wrinkled by unnatural gullies, frown disapprovingly upon the substitution of herds of domestic woollies for the little bands of wild bighorns that once scanned the glorious landscape from their crests. Restoration is past due.
One effort was made, in 1933, by the State Department of Game and Fish to re-establish bighorns in the Pecos high country. Six animals, two bucks and four ewes, were obtained through the courtesy of the Canadian National Park Service from Banff, Alberta, Canada, and released at the west base of the range. A year later the two rams were seen by Forest Ranger J. W. Johnson at the head of the Pecos on the Santa Barbara Divide, but they have not been heard of since and it must be presumed they met the same fate as their native predecessors. With the material reduction of the number of domestic sheep permitted to summer graze this extremely high vulnerable area and the elimination of the dread scabies from the herds, there is now a good possibility that the Rocky Mountain bighorns might yet be restored to their hereditary range. God speed the day!
Ram

My Heart Belongs to Nature

I'll give the last word to the man who told those great stories on the patio of New Mexico Wildlife Center – and in his own voice, to boot.

Burning Fossil Fuels Almost Ended All Life on Earth - The Atlantic

This would be a great read even if it were just science fiction. Beautifully written, start to finish.

Burning Fossil Fuels Almost Ended All Life on Earth - The Atlantic:
Unsurprisingly, there’s no life in these ghastly rocks (even most plant life checks out at temperatures not much more than 40 degrees Celsius), making them exceedingly difficult to date.
“There’s absolutely nothing to date in any of these rocks because everything’s dead,” says Knapp. “But what we can say is that this is definitely Permian.”
...
“I see [a few] possibilities. The first is that things just really got that crazy. Shit happened. The second is that we just really don’t understand positive feedback loops yet. That’s the scary option. The third is that you can’t do it without a supercontinent. We need to be studying these time periods when carbon dioxide caused problems, because right now we don’t understand them at all. It should be a national priority to study the Permian to figure out what the hell happened.”
...
At the top of the canyon the rocks gave up their Martian hue at long last, and were etched with the geological traces of tranquil lakes and river channels and even dinosaur footprints. Up in those rocks the Earth was finally recovering, and the reptiles of the Earth’s most storied age—the Mesozoic—were making their tentative claims to a world that they would come to rule for more than 100 million years. But down here along the dusty trail was the end of the Permian, and the planet was still fighting for its life.
...
Their precious cargo was the lifeblood of civilization. The empty train cars were returning from the nodes of civilization, like spent red blood cells, to this giant, unyielding pump of geological energy in the prairie... They were shuttled along the infrastructural aorta before branching into capillaries where they’d deliver their carbon to far off power plants to be metabolized near cities, by metropolitan mitochondria.

The phrase "global weirding", referring to the strange signs in the fossil record leading up to the Permian extinction, recurs in the article. I can't help thinking that would make a great name for a science-explainer YouTube series...

Trump Administration’s Strategy on Climate: Try to Bury Its Own Scientific Report - The New York Times

Trump Administration’s Strategy on Climate: Try to Bury Its Own Scientific Report - The New York Times:

In publishing the assessment, White House officials made a calculation that Mr. Trump’s core base of supporters most likely would not care that its findings are so at odds with the president’s statements and policies.
That view is supported by Steven J. Milloy, a member of Mr. Trump’s E.P.A. transition team who runs the website junkscience.com, which is aimed at casting doubt on the established science of human-caused climate change. “We don’t care,” he said. “In our view, this is made-up hysteria anyway.”

 

From Mann, Michael. The Madhouse Effect: How Climate Change Denial Is Threatening Our Planet, Destroying Our Politics, and Driving Us Crazy (Kindle Locations 1248-1257). Columbia University Press. Kindle Edition:
[Steven J.] Milloy is no scientist, but he’s darned good at playing one on television — Fox News, to be specific — where he is presented as an environmental science expert. Milloy, in this capacity, regularly calls out the “junk science” implicating tobacco products in human health ailments, pesticides in environmental ailments, and fossil fuels in our current planetary ailment.
What Milloy has failed to disclose while busy presenting himself as an independent “junk science” expert on Fox News is that, as noted earlier, he has accepted payments from Phillip Morris, ExxonMobil, and Syngenta for his advocacy efforts. When journalist Paul Thacker reported these facts in the New Republic in 2006, he also reported the reaction from Fox News, which claimed to be unaware of the financial ties and gave Milloy the lightest of slaps on the wrist, conceding only that “any affiliation he had should have been disclosed.”

Natural gas firms have a proposal to convert home heating to hydrogen | Ars Technica

Good for the U.K.:

Natural gas firms have a proposal to convert home heating to hydrogen | Ars Technica:

The UK has been more aggressive about curbing carbon emissions than the US. In 2015, the country stated that its goal was to close all coal-fired power plants in the country by 2025, and in 2017, the UK electrical grid had its first coal-free day.

I have wished for most of my adult life that the leadership of my country could see economic advantage in pushing toward clean energy, increased energy efficiency, and so on.

If you follow the Fully Charged show on YouTube, by now you've seen lots of ways in which the U.K. is pushing ahead of the U.S. EVs, home batteries and smart grid technology, and more - there's a lot of innovation around energy production and efficiency in western Europe in general.

Extreme Heat Event in Northern Siberia and the coastal Arctic Ocean This Week – Ocean's Wrath

Extreme Heat Event in Northern Siberia and the coastal Arctic Ocean This Week – Ocean's Wrath:

An extreme heat event for this particular region…with high temperatures of greater than 40 degrees F (greater than 20 C) above recent normals…will impact the coast of the Arctic Ocean (specifically the Laptev Sea and Eastern Siberian Sea) Wednesday-Friday. This will generate maximum daily temperatures as high as 90-95 degrees (32-35 C) near the open ocean coast! Yes,  you read that correctly.
Meanwhile we continue extracting and leaking methane into the atmosphere. We continue generating and releasing CO2 at a high rate. Here in the United States, when we could be choosing representatives who have even slight interest in this problem, we are busy voting for the end of democracy. I marvel at our stupidity.

"Be a Good Ancestor"

China made solar panels cheap. Now it’s doing the same for electric buses. - Vox:

The rapidly growing megacity of Shenzhen, China, was choked with diesel pollution in the early 2010s. Though buses were just 0.5 percent of the city’s vehicles, they were responsible for 20 percent of the air pollution. So, as the World Resources Institute recounts, Shenzhen electrified them. All 16,359 of them.
It got there through some cleverness — they planned out charging infrastructure and pushed manufacturers to offer lifetime warranties on batteries — but mainly through government subsidies, which covered up to half the upfront cost of the vehicles.
In 2013, China was bopping along with 1,700 BEBs. ...it realized that its rapidly expanding urbanization could not continue to rely on diesel buses, lest it make an already crippling air-pollution problem even worse.
So it decided to make electric buses a thing. How? By dumping a giant pile of money on the problem, subsidizing the purchase of more than 350,000 BEBs in the following four years.
Other cities are beginning to get on the BEB bandwagon as well.
[BNEF writes that] “Paris aims to electrify all of its 4,500 buses by 2025, Copenhagen has committed to procure only zero-emission buses from 2019, and Los Angeles has the same target for its fleet of 2,200 buses by 2030.”
sometimes problems are big and urgent, you need scaled-up solutions quickly, and you just don’t have time to mess around. China didn’t nudge its solar industry, it kicked it in the pants. Now it’s doing the same to the BEB industry.
As economists will rush to point out, there have been enormous inefficiencies and waste along the way, money lost on graft or junk technology. Solar has often been poorly installed or curtailed. According to BNEF, some 43 percent of the BEBs allegedly produced in China in 2015 were basically fraudulent.
[China] rightly recognized that the problems (coal and diesel pollution) are intensely urgent and it’s not that huge a mystery how to solve them.
Amortized over the next 50 to 100 years, the next several generations of humanity, the cost of transition are a screaming deal at almost any price. It’s just a matter of learning (or perhaps relearning) to take a long-term view of human interests — to be a “good ancestor,” as they say.
